Each of the three main sections has a 'tour' facility for easier navigation through the pages - clicking on the small icons at the corners of each page will move to the next or previous page in that section.
Upcoming public demos, events etc. I'll be participating in
none at present
I can often be found lurking or presenting at Dorkbotlondon meetings.
Want to know what's inside a
baggage X-ray scanner?
Or a Pill
camera? Or why it's a
really bad idea to take apart
a hydrogen fuel cell....?
